Sialuria is an uncommon condition with varying developmental impacts. Newborns with this disorder often exhibit neonatal jaundice (yellowing of the skin and eyes), hepatosplenomegaly (enlarged liver and spleen), and microcytic anemia (abnormally small red blood cells). Some may also present with a flattened face and "coarse" facial features. Delayed development and hypotonia (poor muscle tone) have also been observed in some cases.

Sialuria in young children is often accompanied by frequent upper respiratory infections, dehydration, and gastroenteritis (stomach upset). Seizures and learning disabilities may emerge in older children. However, intellectual development can be near normal in certain affected individuals.

The symptoms of sialuria differ significantly from person to person. Many complications associated with this condition seem to lessen as individuals get older, although the long-term consequences are not well understood. It's possible that some adults with sialuria are never diagnosed because they only experience very mild symptoms or no related health issues.

Inheritance:

Sialuria follows an autosomal dominant inheritance pattern. This means that only one copy of the mutated gene in each cell is enough to cause the condition. The majority of reported cases occur in individuals with no family history of the disorder, likely resulting from new gene mutations.
